Ransomware Removal

I wrote this article to help you remove Ransomware. This Ransomware removal guide works for all Windows versions. ransomware is the most recent reincarnation of CrySiS ransomware. The insidious program gets its name from the email account used for communicating with victims. The creators of ransomware leave a notification for the unfortunate users who have allowed the virus to get past their guard. The message is called a ransom note. The attackers demand a certain sum to provide the unique key for unlocking the encrypted files. The payment is referred to as a ransom, hence where the name of this type of infection derives from. An alternative term to ransomware is win-locker. ransomware uses a combination of AES and RSA algorithms to generate a public encryption key and a private decryption key. The win-locker targets text documents, images, audios, videos, archives, databases, logs, and other file types. All infected objects have a custom file extension appended to their names. The suffix is created using the formula: .[email address].wallet. Here would be the best time to mention that the secluded program does not formally introduce itself. Malware experts use the email address or the custom file extension as a facilitated identifier. Hence why the latest reincarnations of CrySiS are all referred to as Wallet ransomware.

Like all previous builds of the win-locker, ransomware gets distributed via spam emails. The sender hides the furtive program behind an attachment. The file can be listed as a recommended letter, a receipt, an invoice, a bill, a fine, or another piece of documentation. The fake message could seem genuine. To give their email legitimacy, spammers often write on behalf of real organizations. They can misrepresent the national post, the local police department, a courier firm, a bank, a government branch, or a social network. To check whether a given message is reliable, proof the sender’s contacts.

The creators of ransomware have devised two files for the sole purpose of notifying victims about the situation. The win-locker replaces the desktop background with a custom wallpaper. The image, titled README.jpg, engages users’ attention and directs them to the ransom note. The text file, called README.txt, lays out the message of the cyber criminals in greater detail. Still, you have to contact them in order to receive complete payment instructions. After sending the request, you will have to wait for a while. In the response, the hackers will inform you exactly what you are required to do.

The owners of ransomware ask for a ransom ranging between 0.5 BTC and 2.0 BTC. Converted, this corresponds to the interval of $520.45 to $2,081.80 USD. As with national and multinational monetary units, the exchange rates for cryptocurrencies fluctuate on a daily basis. The current trend is for Bitcoins to climb up the charts. The interest in this currency is progressively growing due to the high level of security it provides. The premium security is also the aspect which cyber criminals exploit. Bitcoin trading platforms do not require users to list personally identifiable information (PII) in their accounts. In addition, they do not support tracking. The thieves can collect ransoms without worrying that they could be tracked down.

Paying a ransom is a risky endeavor for the simple reason that there are no laws or regulations to fall back on. The proprietors of ransomware may not send the decryption key. Over the years, we have witnessed many cases of attackers taking a ransom and running with it. You could end up suffering further losses, if you agree to their terms. The best you can do is to uninstall ransomware with the help of an anti-virus program and try to recover your data on you own. There are several tools listed below which could be able to restore your files from their shadow volume copies. Ransomware Removal

Method 1: Restore your encrypted files using ShadowExplorer
Usually, Ransomware deletes all shadow copies, stored in your computer. Luckily, the ransomware is not always able to delete the shadow copies. So your first try should be restoring the original files from shadow copies.

  1. Download ShadowExplorer from this link:
  2. Install ShadowExplorer
  3. Open ShadowExplorer and select C: drive on the left panelshadowexplorer
  4. Choose at least a month ago date from the date field
  5. Navigate to the folder with encrypted files
  6. Right-click on the encrypted file
  7. Select “Export” and choose a destination for the original file

Method 2: Restore your encrypted files by using System Restore

  1. Go to Start –> All programs –> Accessories –> System tools –> System restore
  2. Click “Nextsystem restore
  3. Choose a restore point, at least a month ago
  4. Click “Next
  5. Choose Disk C: (should be selected by default)
  6. Click “Next“. Wait for a few minutes and the restore should be done.

Method 3: Restore your files using File Recovery Software
If none of the above method works, you should try to recover encrypted files by using File Recovery Software. Since Ransomware first makes a copy of the original file, then encrypts it and deletes the original one, you can successfully restore the original, using a File Recovery Software. Here are a few free File Recovery Software programs:

  1. Recuva
  2. Puran File Recovery
  3. Disk Drill
  4. Glary Undelete
